The issue was caused by the alpha animation applied to the bubble bar. Added code to check if the alpha applied to the bubble bar is less than 1 and instruct child bubble views not to provide a shadow outline in such cases. While this is not a full fix, but rather an improvement, b/345490679 should introduce a proper fix.
